What is Answer Engine Optimization?

AEO, Answer Engine Optimization, is the practice of structuring your content so that AI-powered engines like ChatGPT, Google AI Overviews, Perplexity, and Claude choose your website as a cited source when answering user questions.

Traditional SEO is about ranking. AEO is about being cited. Those are different things, and the gap between them is growing fast.

The shift that's happening

In 2024, for the first time, a meaningful share of search queries never reached a search result page. Users asked ChatGPT. They asked Perplexity. Google's AI Overview answered the question before anyone scrolled. The click never happened. For brands and publishers, this is a structural shift in how discovery works. If an AI answers the question and cites someone else, you didn't just lose a ranking: you lost the conversation.

How AEO differs from SEO

SEO optimises for ranking signals: links, authority, keywords, technical health. AEO optimises for citation signals: factual density, clear entity definition, FAQ structure, schema markup, and authoritativeness. A page can rank #1 and never be cited by AI. A page can sit at #6 and be cited constantly, because it's structured in a way that AI finds easy to extract, trust, and reference.

What AEO actually involves

  • Writing content in a direct question-and-answer format
  • Using structured data (JSON-LD schema) to define who you are, what you do, and what you know
  • Building factual density: specific stats, dates, definitions, and named entities
  • Earning citations from authoritative sources so AI engines treat your domain as trustworthy
  • Matching the exact phrasing patterns that AI engines use to extract answers
  • The window is now

    AI search is still establishing its source preferences. Early AEO work has an outsized effect, because you're competing with brands that haven't started yet. That window won't last long.
